Abstract

Riau University hospital is an educational infrastructure institution and health institution in collaboration with Riau University. Most of the patients treated at Riau University hospital are people from the riau university community such as campus staff, lecturers and students. Outside communities that are not from the community of UNRI campus have a small percentage to treat in hospitals Riau University. Another problem, for patients who are located far from the hospital of Riau University will have difficulty because patients who want to seek treatment at the University of Riau hospital and conduct consultations with the desired doctor can not know the schedule of the doctor on duty, so the patient must go to the hospital first to find out the schedule of the doctor's duties on the day. Therefore, a consultation application is needed that can help solve the problems described. This research uses waterfall method to help the process of making consulting application. The data collection is obtained by interview method and observation directly to the field. The consulting application was created using Android Studio with the Java programming language and eXtensible Markup Language (XML), as well as Firebase as a database. Application testing uses the User Acceptance Test (UAT) method to see the results of application creation based on user ratings. Based on the results and tests carried out, obtained an android-based UNRI hospital consultation application. This consultation application can be used by patients to view schedules and consult online with doctors working in UNRI hospitals. This application is expected to help prospective patients can seek treatment and consult a doctor easily. Keyword : Java, XML, Android

Abstract

Keeping various types of ornamental fish in the aquarium must be considered when maintaining one of them is in feeding fish. For some people who have quite a lot of hectic activities, it can be a difficult task to handle fish feed when leaving the house for extended periods. Therefore, a system was designed to assist aquarium owners in regular feeding of fish, and aquarium owners can monitor fish feeding remotely. This tool works according to the fish feed schedule with a frequency of twice a day, in the morning and evening. This study uses software and hardware consisting of ESP8266 as the main control, ultrasonic sensor as a feed distance meter, servo motor as a container valve opener, RTC (Real Time Clock) as a scheduler, and a buzzer as an alarm. When the internet is connected to the ESP8266, the data will be sent to a telegram to notify the owner. Based on the test results, this fish feeding tool can work according to a pre-arranged schedule option, and is able to display notifications to the telegram application. The system that has been designed can already monitor the feeding of fish and provide notification results in the form of information on the availability of fish feed and notification of the feeding schedule for fish through the telegram application on the user's smartphone.Keywords : ESP8266, Internet of Things, Telegram

Abstract

Communication between vehicles plays an important role in increasing comfort such as reducing vehicle density and security, namely regulating vehicle speed for drivers and passengers. Advances in technology offer concepts to improve comfort and safety in driving, namely Vehicular Ad Hoc Network (VANET). However, VANET has network characteristics where the network nodes are moving very fast. In this research, a comparison of the performance of two topology-based routing protocols is performed. The topology in this research are : Optimized Link State Routing (OLSR) and Dynamic source routing (DSR) on VANET. (OLSR) is a proactive routing protocol that determines the routing table by updating every time a link changes, (DSR) belongs to a reactive routing protocol that only selects paths or updates paths only when there are new route or when a route is cut off. Both routing protocols are simulated using Network Simulator 2 (NS-2) with a scenario of changing the number of nodes. The two protocols are compared based on the parameters of the Packet delivery ratio and end-to-end delay. From the results of the study it was found that the DSR routing protocol has a better PDR value of 99.80% compared to OLSR of 99.53%, the average end-to-end delay from DSR is 0.13 seconds, while OLSR is 0.12 seconds. This shows that the DSR routing protocol is superior to the packet delivery ratio and OLSR routing protocol excels at end-to-end delay Keyword: VANET, Proactive, Reactive, OLSR, DSR
